Wheel



Patented Nov. 26, 1935 UNITED STATES WHEEL Victor W. Kliesrath, South Bend, Ind.,asslgnor to Bendix Aviation Corporation, South Bend, Ind., a corporation oi Delaware Application April 29, 1932, Serial No. 608,283;

This in ention relates to wheels and more particularly to wheels for use with low pressure tires.

' Broadly, the invention comprehends a. wheel comprising a hub having a flange supporting a radial load carrying disc provided with a .rim

arranged to support an auxiliary rim. The rim and the auxiliary rim are arranged in spaced relation to provide an annular ventilating space between them. Ventilation is eflected through suitable openings in the rim communicating with the annular ventilating space and through louvers in a detachable retaining flange secured to the radial load carrying disc for supporting the auxiliary rim.

5 The structure further contemplates a highly desirable brake drum including two or more rings orbands supported by a resilient means secured to the inner periphery of the rim. It has been found that brake drums of this particular struc-,

20 turemay readily become self-adjusting and selfaligning, and this is an important factor.

An object of the invention is to provide a wheel,

. structure including a rim and an auxiliaryrim arranged in spaced relation and means for ven- 5 tilating the space between the rim and the auxiliary rim.

Another object of the invention is to provide a wheel structure including a self-adjusting and self-aligning brake drum.

0 A feature of the invention is a ra load carrying disc having a rim, an auxiliary rim supported thereby in spaced relation thereto, and a detachable retaining ring for the auxiliary rim having means for supporting the auxiliary rim 35 and directing currents of air between the rim and the auxiliary rim.

Another feature of the invention is a wheel having a rim, and a drum including a plurality of bands resiliently supported on the rim of the 40 wheel.

other objects and features of the invention will appear from the following description taken in connection with the drawing, which forms a part of this specification, andin which:

' 5 The drawing is a vertical sectional view of a wheel illustrating the various parts that go to make up the present invention. I Referring to the drawing for more specific details of the invention, Iii represents an axle hous- 50 mg having the conventional flange E2 to which is bolted or otherwise secured a backing plate or dust shield it. This structure which may be of any preferred type constitutes no part of the present invention.

An axle it supported in the axle housing it has 5 formed thereon a shoulder it and a spindle 20. This spindle has positioned thereon for rotation a wheel embodying the invention. As shown, the wheel includes a hub 22 having suitable bearings 26 and 26. The bearing 24 engages the shoulm der it on the spindle, and the bearing 26 engages a retaining nut 28 threaded on the end of the spindle.

The hub of the wheel has formed integral therewith-a radial flange it, to which is suitably secured a radial load. disc 32 provided with a rim it having a retaining flange 36. The rim it is apertured asindicated at 38, the object of which will hereinafter appear. An auxiliary rim it is suppblted in spaced relation to the rim 36 to provide an annular ventilating space. The auxiliary rim is supported by the retaining flange 3t and a detachable retaining flange 42 secured on the disc 32. The detachable retaining flange has a head 6 3 fitting snugly between the rim and the a r s 1 rim and louvers 46 are arranged in the ded portion of the detachable retaining e louvers function as fan blades which cause rapid circulation of air through the annular space between the rim to and the auxiliary rim it to efiectively cool these elements, and in addition thereto force currents of air through the openings 3% to circulate about the drum and to efiectively cool the e. U

The rim has secured on its inner periphery a cushion in the form of a flexible channelled member 48 to which is suitably secured a drum including corresponding rings or. hands 50 adaptable for cooperation with a suitable friction element 82. The supporting means for the bands is such that the bands may readily become self-adjusting and self-aligning; hence, more eflicient cooperation with the friction element.

Although this invention has been described in. connection with certain specific embodiments, the principles involved are susceptible of numerous other applications that will readily occur to persons in the art. The invention is,

2 therefore, to be limited only as indicated by the scope of the appended claim.

Having thus described the various features of the invention what I claim as new and desire to secure by Letters Patent, is:

A wheel comprising a radial load carrying disc,

a lateral extending rim on the disc having radial perforations and a retaining flange, a detachable retaining flange on the disc, an, auxiliary rim supported by the flanges in spaced relation to the rim, lcuvers in the detachable retaining flange communicating with the space between the rims, a brake means spaced from the inner periphery of said laterally extending rim and means to secure said brake means in said spaced relation.
